    Name:    System 903, System 904, System 905 & System 906.

    Basic hardware for all systems:
    -------------------------------

    CPU =  1x SY6502 @ 625 kHz.  ; M6502 compatible.
    SND =  1x AY8912 @ 1.25 MHz. ; AY-3-8910 compatible.
    I/O =  2x PIAs SY6520/6820   ; M6821 compatible.
    CRCT = 1x SY6545             ; M6845 compatible mode. It doesn't seems that is using
                                 ; the first 4 bits of register R03 (HSync width).

    CLK =  1x Xtal @ 10 MHz.     ; CPU clock = 625 kHz.
                                 ; SND clock = 1250 kHz.
                                 ; PXL clock = 5000 kHz.

    PRG ROMS at locations u5, u6, u7, u8, u9.
    GFX ROMS at locations u67(cg0), u68(cga), u69(cgb), u70(cgc).

    Inputs use 6 lines from 6520 PIA's port, and each one is multiplexed x4.
    Another line from the same PIA (bit 6) is out of the multiplexed system, and is directly
    connected to the settings DIP switches (SW1-5).

    Some games like Keno and Big Game, also have a key encoder peripheral processor
    based on a 8035, and 1x ROM 2516/2532.



    System 903/904 specific:
    ------------------------

    1x MC6850 (ACIA) for serial communication.

    ROMs u5 to u9 are 2516.

    System 903 has 3x 8 DIP switches banks, wired to ACIA6850, PIA1, and AY8912 respectively.
    System 904 has 2x 8 DIP switches banks, wired to ACIA6850 and PIA1 respectively.
    Some 903 based PCBs like TUNI games only have 1x 8 DIP switches bank, wired to PIA1.

    Systems 903/904 PCBs have 3 pots to control R, G, and B independently.
    However, it seems to be only related to the background color.

    CPU lines A14 and A15 are not connected, so the CPU is addressing only 16KB.



    System 905 specific:
    --------------------

    ROMs u5 to u9 are 2532.

    1x 8 DIP switches bank, wired to PIA1.

    CPU line A15 is not connected, so the CPU is addressing only 32KB.

    --- General Notes ---


    Gaming Draw Poker:

    Gaming Draw Poker, formerly known as Jack Potten's poker, is an evolution of the
    mentioned game. It was created by Cal Omega in 1981 for Casino Electronics Inc.
    Cal Omega was bought out by CEI (Casino Electronics Inc.), and CEI was bought by UCMC.

    This is the most famous game from Cal Omega 903 System. In the test mode you can see
    the name "Gaming Draw Poker", but in the manual figure as "Casino Poker". Also in some
    game lists you can see it with another name: "Arcade Poker".

    The game uses the same GFX set that Jack Potten's Poker for cards and has similar
    layout, but the game is different and the old discrete pitched sounds were replaced
    with a better set of sounds through a AY8912 implementation. The empty socket in
    the PCB is for future upgrades instead of sound ROM, since sounds are hardcoded.

    Inputs are multiplexed and selected through PIA1, portB.


    Some instructions....

    * Some versions have a STAND button to conserve all cards without discards.

    * To enter to the Input Test Mode press TEST MODE (key 9).
      Press DISCARD1 (key Z) + DISCARD2 (key X) + DISCARD3 (key C) to exit.

    * To see the last hand played and stats, press DISPUTE (key 0).
      Press DEAL/DRAW button to exit.

    * Depending of the game version, TEST MODE & DISPUTE buttons only work if the door
      was previously opened. To do that, you must keep pressed DOOR OPEN (key D).

    * To pass coin and hopper errors press DOOR OPEN (key D). If the hopper is empty,
      keep pressed DOOR OPEN and press HAND PAY (key O)

    * For payout, press COLLECT (key I) and then PAYOUT for each credit (manual mode).



    El Grande - 5 Card Draw:

    This game was created by Tuni Electro Service and was licenced to E.T. Marketing,Inc.
    This is the new version. The old one is still undumped, but looks like Golden Poker D-Up.

    Flyer: http://www.arcadeflyers.com/?page=thumbs&db=videodb&id=4542

    The AY8912 is mapped to 0x840/0x841 but the game lacks of credits and bet sounds.
    The rest of sounds are ok. Maybe the missing ones are generated by discrete circuitry.

    Inputs are multiplexed and selected through PIA1, portB.

    There aren't meter and stats modes. Only for amusement, so... no payout.
    To clear credits press F2.
    To enter to TEST MODE press F2 twice. Press HOLD 1 + HOLD 2 + HOLD 3 to exit.

    -- Gaming Draw Poker --------------------------------------------------------

    Program roms are roms 23*.*, on the board, there is a number near each roms
    looks to be the address of the rom :

            23-91   1800
            23-92   2000
            23-93   2800
            23-94   3000
            23-9    3800

    Graphics are in roms CG*.*, there is no type indication on these rams, i hope
    i read them correctly.

    There is also 3 sets of switches on the board :

            SW1     1       300     SW2     1       OPT1
                    2       600             2       OPT2
                    3       1200            3       OPT3

                    5       4800            5       OPT5

                    8       -               8       +HPOL

            SW3     no indications on the board

    The sound rom is missing on the board :(
